RESUMO
The asymmetric unit of the title compound, C(9)H(4)S(7), contains two independent mol-ecules, in one of which the central five-membered ring is disordered over two orientations in a 0.924â (3):0.076â (3) ratio. The mol-ecular skeleton is almost planar: the average distance of the atoms from their mean plane is 0.128â (7)â Å in the ordered mol-ecule, and 0.088â (5) and 0.123â (2)â Å in the major and minor disorder components, respectively. The ordered and disordered mol-ecules form separate columns by stacking along the b axis. Adjacent columns inter-act via short Sâ¯S [3.33â (2), 3.434â (3), 3.444â (2), 3.503â (2), 3.519â (3) and 3.53â (4)â Å] and Sâ¯H [2.814â (2), 2.87â (7), 2.92â (2), 2.9269â (18), 2.93â (2), 2.94â (2), 2.939â (2), 2.967â (2) and 2.974â (1)â Å] contacts.
